“	For some time now, Aftokrator has been researching how to implant Trigger-equipped Trion Receptors into the heads of young children to create humans with exceptional trion abilities.	”

Trion Receptor (トリオン 受(じゅ)容(よう)体(たい), Torion Juyōtai ^?), also known as Trigger Horns (トリガー 角(ホーン), Torigā Hōn ^?), are a type of Trigger-equipped implant used by Aftokrator Neighbors. They are generally referred to simply as Horns (角(ツノ), Tsuno ^?).

Appearance

Trion Receptors are shaped like horns of different animals, such as rams or deer. They are normally white, but turn black if the owner uses a Black Trigger. The horns of adults are usually a few inches long, but those of children may barely protrude out of their skulls. Although they seem to normally come in pairs, this is not always the case.

Overview

Trion Receptors are a military secret in Aftokrator. Seven years prior to the invasion of Earth, they were already functional, however Viza may not have them due to his trion gland having stopped developing long before they were created. Currently, it is common practice for noble families in Aftokrator to buy children with high trion levels and implant them with horns in order to use them as future soldiers. It was implied that Trion Receptors are either replaced with bigger ones as the owner ages, or that they grow with them.

Abilities

Trion Receptors are implanted in Aftokrator neighbors at an early age to dramatically improve their trion capacity and quality as they grow, allowing them to use more powerful Triggers for a longer amount of time and with greater efficacy. Researches have also been done to use horns to increase compatibility with Black Triggers. The capabilities of a horned fighter far exceed those of a normal Trigger user.

Trion Receptors also collect biological data on the owner. If the latter used a Black Trigger, the information stored in the horns can be used to find other compatible individuals. Information can be accessed by a third party without direct contact with the horns themselves.

However, Trion Receptors can be dangerous for the one who receives them. If they take root in the brain, they will gradually spread, affecting the personality of the owner and eventually killing them. A symptom of the process is the sclera of the owner changing color.

Combined with their data-collecting function, this side effect makes it possible to create a "copy" of a Trion Receptor possessor by implanting the horns, retrieved from the real body, in a compatible host, such as a Rad. The personality and memories of that individual will be preserved even if they themselves are dead.

Hyuse's horns serve the same function as a Trion Body.

Just like a Trion Body, the horns will interpret the words on both the receiving and speaking end regardless if the other person is in a trion body.

Users

According to Replica and Enedorad, children and fighters with horns are a common sight in Aftokrator. Out of the 6 humanoids sent to attack Earth, 5 had Trion Receptors: Ranbanein, Hyuse, Mira, Hyrein and Enedora. Following the latter's demise, the his horns were transplanted into a Rad by Border.

Trivia

• In biochemistry and pharmacology, a receptor is a protein molecule that receives chemical signals from outside a cell.
• If a person pulls/pushes a user's horns, their head and the base of the horns wouldn't hurt much, but if they are moved too much it will hurt their neck.
